• 20:2120:21, 20 March 2021 diff hist −15 m Posse comitatus →No indications as to why it is a "broad" definition to include posses: extrajudicial killings are not legitimized simply by being organized by a sheriff

27 December 2016

• 18:3618:36, 27 December 2016 diff hist +15 m Universal enveloping algebra The previous statement was strictly mathematically wrong: the PBW theorem *does* state that the two are isomorphic as algebras (hopefully it will be obvious to future editors that at least the associated graded algebra is commutative).
• 18:3318:33, 27 December 2016 diff hist +35 Forgetful functor →Left adjoint: Free

26 December 2016

• 01:0301:03, 26 December 2016 diff hist +205 Simple Lie group The B and D series erroneously claimed that SO(n) was simply connected (this is never true: fundamental group = Z for n=2 and Z/2 for n>2).

• 21:3721:37, 28 May 2016 diff hist +64 m Ham sandwich theorem link to orientation + claim that this is the same thing as this article's definition of "positive side"

27 May 2016

• 21:4921:49, 27 May 2016 diff hist +33 m Betteridge's law of headlines untrue-->Liar's paradox (this is what the cited article's title actually does) Tag: Visual edit

19 May 2016

24 November 2015

• 07:0307:03, 24 November 2015 diff hist −22 m Exterior derivative →Definition: I've never seen d_X notationally used; I believe both mathematicians and physicists usually would wrote $X(f)$.

6 February 2014

• 23:3623:36, 6 February 2014 diff hist −46 Category (mathematics) Deleted reference to 'category of being' - this has nothing to do with category, apart from the word 'category'

21 December 2013

• 20:1920:19, 21 December 2013 diff hist +99 m Lindelöf space Adding Munkres' book to references; it covers Lindelof spaces in detail
